I've searched for this topic and a few came up but it didn't help me. My brother completely messed up the C drive and formatted everything. All of vista is gone and I can't access my computer. When I try to boot from the XP disc, it should have showed a 'press a key to continue' or something like that but it didn't. It skips that part and tells me that bootmgr is missing.
The only thing I have left in the HDD is my D drive with some games on it. How can I fix this?
